Want the best permanent valve stem on the market? Our Ultimate Valve System is it!

It is a full 1/2″ shorter than our original Permanent Valves, lowering the risk that it will contact hazards on the trail. If it does, the high strength will further protect you against a valve stem break.

• Fits standard .453 wheel openings (everything from bicycles to trucks)
• Installs in about 1 minute
• Recommended 10-15 inch lb torque(similar to putting a bottle cap on tight), if gasket begins spinning it should be tight enough

• Quality 360 brass components
• Patented and Made in the USA
• Colby Valves are not compatible with Indian Motorcycle stock wheels
